This is just one of the military planes Syrian rebels claim to have shot down in this latest video posted to a social media website whose content Reuters cannot independently verify.

Other video shows a tank that rebels say they targeted in the mountains of Deir al Zoir.

At least 200 people were killed over the weekend according to the Syrian Observatory for Human Rights.

Opposition activists reported increased attacks on Aleppo and Homs where a car bomb killed at least 20 people and wounded dozens.
